A vacuum insulated structure including a tube having an outer wall, a jacket surrounding the tube to enclose an annular insulating space, the jacket having an end that terminates at the outer wall of the tube, a seal formed between the end of the jacket and the tube to preserve a vacuum within the insulating space, and a fitting affixed to one of the tube and the jacket for coupling the vacuum insulated structure to an external device. A method of making a vacuum insulated structure including forming a tube and a jacket, positioning the jacket over the tube to form an annular insulating space, with an end of the jacket being positioned adjacent to an outer wall of the tube to form a vent, causing air to escape through the vent, sealing the vent, and affixing a fitting to one of the tube and the jacket.

1. A vacuum insulated structure comprising: a tube having an outer wall;a jacket surrounding the tube to enclose an annular insulating space between the tube and the jacket,the jacket having an end that terminates adjacent to the outer wall of the tube, and the jacket being brazed to the outer wall
1. A vacuum insulated structure comprising: a tube having an outer wall;a jacket surrounding the tube to enclose an annular insulating space between the tube and the jacket,the jacket having an end that terminates adjacent to the outer wall of the tube, and the jacket being brazed to the outer wall of the tube so as to form a seal between the jacket and the outer wall of the tube to preserve a vacuum within the insulating space; anda fitting affixed to one of the tube and the jacket for coupling the vacuum insulated structure to an external device, wherein the seal is formed by a first vacuum brazing process and the fitting is affixed to the jacket by a second vacuum brazing process. 2. The vacuum insulated structure of claim 1, wherein the first and second vacuum brazing processes are performed concurrently. 3. The vacuum insulated structure of claim 1, wherein the first and second vacuum brazing processes are performed sequentially. 4. The vacuum insulated structure of claim 1, wherein the fitting is selected from the group consisting of: a welding socket, a female threaded fitting, a male threaded fitting, a compression fitting, a flange fitting, a custom fitting, and combinations thereof. 5. The vacuum insulated structure of claim 1, wherein the fitting is affixed near an end of the jacket. 6. The vacuum insulated structure of claim 1, wherein the fitting is affixed at an intermediate position along the jacket. 7. The vacuum insulated structure of claim 1, wherein the fitting is affixed to the tube. 8. A vacuum insulated structure comprising: a tube having an outer wall;a jacket surrounding the tube to enclose an annular insulating space between the tube and the jacket,the jacket having an end that terminates adjacent to the outer wall of the tube, and the jacket being brazed to the outer wall of the tube; so as to form a seal formed between the jacket and the outer wall of the tube to preserve a vacuum within the insulating space; anda fitting affixed to one of the tube and the jacket for coupling the vacuum insulated structure to an external device,wherein the fitting is affixed to an inner wall of the tube. 9. A vacuum insulated structure comprising: a tube having an outer wall; a jacket surrounding the tube to enclose an annular insulating space between the tube and the jacket, the jacket having an end that terminates adjacent to the outer wall of the tube; a seal formed between the jacket and the outer wall of the tube to preserve a vacuum within the insulating space; and a fitting affixed between the tube and the jacket for coupling the vacuum insulated structure to an external device. 10. A vacuum insulated structure comprising: a tube having an outer wall; a jacket surrounding the tube to enclose an annular insulating space between the tube and the jacket, the jacket having an end that terminates adjacent to the outer wall of the tube; a seal formed between the jacket and the outer wall of the tube to preserve a vacuum within the insulating space; and a fitting disposed within the tube.
